The study Packning i tid och rum (Crowding in Time and Space) is a Master Thesis in Human Geography within Geography, presented at Södertörn University College.The aim is to investigate the connections between time and space, more particularly, geographical changes over time. This is done by focusing on the Study of Land use as a phenomenon and on-going processes in demarcated areas. Distinct areas are given special interest, i.e. how they are used. The study deals with three different kinds of sites in three levels of scale: a market garden, cemeteries and a residential area.The main focus of the study is on the cemeteries.

This thesis examines which function the information technology may have in thechildren's library, with the example from two library computer programmes. One is anexpert system, Hedvig, which will help children to choose and to find books, and theother is a computer game, The mysterious signs, that will teach children library user education.The main question is: What conceptions do the project-leaders, the children'slibrarians and the children have concerning the function of these two programmes in thechildren's library?The study is based upon qualitative interviews with two projects-leaders, fourlibrarians, three computer programmers and twenty-eight children.The theoretical material consists of examples on other library computer programmesfor children developed in Denmark and USA, some American studies in children'sabilities to use computerized information retrieval systems, and studies concerningchildren's relations to computers.The adult's conceptions of the computer programmes are divided into categories asfollows: Democracy, aspect of sex, complement, marketing, reading promotion,development of competence, information technology development, pedagogics, adulteducational activities, compensation and armusement, pedagogics, usefulness,effectiveness and information. These categories shall be seen as the conclusions of the thesis..

Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.

This bachelor thesis aims at investigate how a specified house can optimize its energy consumption.Today the house often stands for the major part of the energy consumption in a consumers? life,whereas an energy optimization creates economic as well as environmental advantages. It is importantto make old houses more energy efficient, but putting high energy demands on new houses could beargued to be more important. The installations functions as both the heart and brain in a house, thusmaking it important to energy optimize these. Since the background describes the importance ofenergy efficiency and optimization in a house, the focus area of this report will be an investigation ofdifferent types of heating systems in order to be able to choose the one most suited for the house.Aspects considered when choosing the heating system was how economic the system is both inservice- and investment costs and how environmental and operational friendly the system is.Through literature reviews there were sufficient information gathered that served as a foundation whencomparing and choosing between the four systems - district heating, pellet-fired boiler, geothermalheating and solar heating.

Every day a large numbers of transactions occur by people with different backgrounds. Insiders? are a part of them and are considered to have an insight in companies that is not accessible to outsiders. This affects the market conditions for the participants when trading stocks, where individual participants regularly have the possibility to earn abnormal returns at the expense of others. Although Sweden, Germany and the United States continually keep developing the insider trading regulation, research shows that insiders? still have the ability to earn abnormal returns.

Modern IT systems tend to become more and more complex, while the number of active systems in companies increases. Furthermore, the number of security-related incidents is at an all-time high. These new conditions impose new demands on organizations. For example, it is no longer possible to manually collect and examine the systems log messages.The purpose of this thesis has been to make a comprehensive study of solutions for automated collecting and managing of log messages, analyze the Swedish Armed Forces specification for solutions for central log collection and management, and evaluating exis- ting solutions. The work consisted primarily of literature studies and evaluations of two of the Swedish Armed Forces of selected products: NetIQ Security Manager and Splunk.

Energy efficiency is important both to reduce costs and to reduce greenhouse gas in the atmosphere. In Sweden 40 percent of the energy consumption is related to the buildings sector. Hospitals are complex buildings with different activities in the same building, which requires flexible technical systems for ventilation, heating and lightning. A quarter of the total energy consumption in Swedish hospitals is related to user activities in the hospitals. Therefore it is not only important to work with operational optimization but also to change user activities, to reduce energy consumption.The objective of this thesis was to examine the user-related energy efficiency work at two care units, at the central hospital in Sundsvall within Västernorrlands County.

The purpose of this literature review was to investigate how the rearing systems influence the behaviour of dairy calves. Calves are social animals that form groups within the herd where play and social licking between calves are important social activities. Suckling is a complex behaviour and essential for the calf's survival. In the modern rearing systems the calf is usually separated from its mother soon after birth. Calves are then kept in individual pens, group pens or, more rarely, with a foster cow.

AbstractThis report describes our ten week long thesis work which is the last task in our education in mechanical engineering at Linköpings University. The project has been performed at Siemens Industrial Turbomachinery AB?s service department. The company which is located in Finspång produces, sells and provides service for steam and gas turbines around the world.The purpose of this project is to help Siemens develop their maintenance programs for two of the auxiliary systems which are a part of the complete steam turbine system. These are lube and control oil systems.The project is restricted to two of Siemens maintenance products, No Stop Check (NSC) and the annual Safety Inspection (SI).

The implementation of large IT-systems is a complex area where many aspects have to be taken into account.KSU, Kärnkraftssäkerhet och Utbildning AB, is a small company in the Vattenfall group that is increasingly being urged to implement SAP, one of the largest ERP-systems on the market. Vattenfalls purpose with SAP is to centralize certain processes within economy that are common to all the companies in the group, this to gain benefits with economics of scale. However, KSU is not convinced that SAP is a suitable system and that the common processes apply to them.The purpose of this degree project is to investigate if SAP is a suitable system and if KSU will benefit from a transition to SAP. Three perspectives were applied to further specify important areas of the main question. From a technical point of view KSU:s demands on a system was mapped against SAP.

Sustainability questions that concern the subjects of environmental and social aspects are increasing in today?s society, and therefore the sustainability report is a way for companies to show their work with sustainability development by working with a clear report and follow up. As the first country in the world, Sweden has decided, as from the financial year of 2008, that all governmental owned companies should present a sustainability report according to the guidelines of GRI. The aim of this essay was to identify and analyze actual events from a sustainability aspect for Vattenfall, from a medial perspective during the time period 2005-2009. We made a content analysis of one company?s sustainability reports during a time period of five years and we connected this to the medias reports of the company from the same period, to see if there were any connections between the subjects that media had elucidated.

The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.

Det här arbetet vill belysa vilka förväntningar användare (inom vården) har inför ett nytt informationssystem (IS) som ska implementeras och vilka faktorer som kan påverka och förändra dessa. För att lyckas med arbetets föresats genomfördes en semistrukturerad intervju av fyra aktiva sjuksköterskor inom Tibro kommuns hemsjukvård, där i december 2004 ett nytt datorbaserat IS (patientjournal) implementerats.Materialet från intervjuerna spelades in med bandspelare, transkriberades och tolkades med kvalitativ innehållsanalys. En granskning av resultatet gav bland annat följande slutsatser:Användare inom vården saknar ofta en formell datautbildning, men besitter ändå kunskap om det datorbaserade informationssystemet, kunskap som de förvärvat genom att ha arbetat med datorbaserade IS under många år. Kunskap och erfarenhet som användarna ofta får förlita sig på när ett nytt IS ska implementeras då tid och resurser saknas för en genomgripande utbildning.Användarnas förväntningar på ett nytt IS påverkas av faktorer, såsom erfarenheter från ett tidigare datorbaserat IS, saklig information och utbildning. Med saklig information menas information som både visar på för- och nackdelar..

There are around 855 000 on-site sewage systems in Sweden and some 1 800 of these are located in the municipality of Sigtuna. The Sigtuna local authority has set the goal that all sewage systems with insufficient function should be improved before the end of year 2010. A malfunctioning on-site sewage system may cause three main problems: spreading of diseases, discharge of eutrophicating compounds and wastage of resources. The municipality strives to reduce these problems already at the stage of granting permits for installation of on site sanitation systems. The municipality has recently adopted new guidelines, which demands certain minimum reductions for different compounds. The guidelines also state that it is preferred that neighboring house-owners cooperate in jointly built and operated sewage systems and that the system should be able to recycle plant nutrients.
